HOME SOLAR - HOW IT WORKS:

Most homes draw their power from a network of transformers and substations that make up the "Grid" that is controlled by utility companies. Solar-powered homes are apart of that grid, but they generate their own power with panels installed directly on the roof. Your homes uses AC currency, and the inverter converts electricity from DC to the AC currency your home runs on. More often than not, the solar panels will generate more power than you need and you'll put that power back into the "grid". This is stored as "power credit" and you can sell it back to the power companies or save it for later use!
